That's a "reflecting" telescope.
An optical telescope collects and focuses visible light from celestial objects like stars, planets, and galaxies. This light is then directed to a detector or eyepiece for observation and analysis.
A telescope uses a mirror to collect and reflect light gathered from celestial objects. The mirror focuses this light to create a magnified image, allowing astronomers to study distant stars, planets, and galaxies with greater clarity and detail.
Yes a telescope collects electromagnetic radiation (light) an then brings this light to a focus so that the source of the light is magnified. The larger the diameter of the telescope, the more light it collects making the image at the focus brighter so as well as magnifying the image a telescope also allows one to see fainter objects.
At the end of the reflecting telescope is a primary mirror. This mirror collects and focuses light from distant objects before reflecting it to a smaller secondary mirror or camera for further magnification or analysis.
The main optical element of a refracting telescope is the objective lens. This lens collects and focuses light from distant objects, forming an image that can be magnified and observed through an eyepiece.
A reflecting telescope "Has a mirror that collects light which is reflected to the eyepiece to show the image".
A Reflecting Telescope.
It collects the light from the object and enlarges the picture using the lense, in other words, the glass at the end focuses on that object so you many see it better.
Refractors use a concave lens to refract the light rays through the main body, off the rectangular prism and into the eyepiece. These telescopes use no mirrors like reflectors (except the triangular prism contains a small mirror but a triangular prism is optional)
An optical telescope (as distinct from, say, a radio telescope). It's possible that the answer was intended to be "a refracting telescope" but reflecting telescopes use lenses as well.
The lenses used in reflector telescope is the concave lens.
An optical telescope focuses and concentrates visible light; radio telescopes focus and concentrate electromagnetic radiation (which means, "light") in the radio part of the spectrum.
